ASH-SIFTERQ Specification of Letters Patent.

Patented Feb. 27, 1906.

Application filed April 17, 1905. Serial No. 255,878.

To all whom it may concern:

Be it known that 1, CHARLES H. Dow, a citizen of the United States, residing in Boston, in the county of Sufiolk and State of Massachusetts, have invented an Improvement in Ash-Sifters, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to an ash-sifter, and has for its object to provide a simple, inexpensive, and efficient apparatus for the purpose specified. For this purpose I employ a rotary reciprocating or oscillating screen located within a casing which is adapted to be fitted over a barrel or receptacle, and provide means for actuating the screen from outside said casing. These and other features of this invention will be pointed out in the claim at the end of this specification.

Figure 1 is a vertical section of a barrel provided with an ash-Sifter embodying-this tus shown in Fig. 1; and Fig.3, a section on the line 3 3, Fig. 1.

Referring to the drawings, a represents a barrel or receptacle for the ashes, upon which is placed an apparatus embodying this invention. The apparatus consists, essentially, of an oscillating or rotary reciprocating screen I), of foraminous material, such as usually employed in ash-sifters, which is suitably secured to a circular frame comprising an annular rim 0 and spokes d, which radiate from a shaft e, to which said frame is fastened to rotate therewith. The shaft 6 is vertically arranged and is mounted to turn on a pivotpin or stud f, projecting from a cross-bar g, secured at its opposite ends to a casing, which is preferably made as herein shown, and consists of a lower section h, which fits over the barrel 0. and is supported by a flange i on its inner side, which rests on the barrel. The upper surface of the section It is inclined, but annular in form, and has riveted, soldered, or otherwise secured to it the upper section 7c,which is annular in shape andwithin which the screen I) is located.

The section k is provided at its highest point with an inlet-mouth m, which communicates with a hopper n,-provided with a cover 0, and at a substantially diametrically opposite point the section k is provided with an outlet-mouth p, from which leads a discharge-pipe g.

The shaft 6 is inclined and extended through the top of the section it and has attached to it a handle 7, which projects beyond the circumference of the casing and into position to be grasped by the operator. The shaft 6 and'the sieve or screen connected therewith is oscillated by reciprocation of the handle, which latter may be limited or ar rested in its movement in opposite directions by stops attached to the top of the casing, which stops may be formed, as herein shown, by the bent ends of a bar 10, which is fastened to the top of the casing. The stops serve to impart a shock to the screen or sieve, and thereby agitate the ashes thereon.

In operation the ashes to be sifted are deposited in the hopper and pass through the inlet-mouth of the casing onto the sieve or screen I), after which the latter is given a rotary reciprocating or oscillating motion by reciprocation of the handle 1". The ashes pass down over the sieve or screen, which is inclined toward its discharge-orifice or outlet-mouth, and the fine ashes pass through the meshes of the sieve into the barrel while the cinders pass out through the mouth 1) and discharge-pipe 9 into the pan or other receptacle located below the same and preferably supported by the hook or projection 12 on the discharge-pipe. The casing fits the barrel substantially dust-tight, and when the cover to the hopper is closed the be sifted without inconvenience. b practically forms a disk whose diameter is substantially equal to the diameter of the casing, so as to fit substantially close and prevent the passage of cinders into the barrel.

1 claim In an ash-Sifter, in combination, a circular casing open at its bottom and closed at its top and sides, said casing having an inletmouth and a discharge-orifice in its side opposite said inlet-mouth, a substantially fiat screen of substantially the diameter of said casing and inclined from the inlet-mouth to said discharge-orifice, a substantially vertical shaft located in said casing and to which ashes may- The screen said screen is secured to rotate therewith, a name to this specification in the presence of support for said shaft secured tlo the said castwo subscribing Witnesses. in Within the same a hand e ocated above th casing and secured to said shaft and stops CHARLES 5 on said casing between which said handle is Witnesses: extended, substantially as described.
